Exporting an Object to an Isatis File

You can export an object to an Isatis1 _file.

Connection with

Isatis SKUA or GOCAD connects to the Isatis database by using the GTXserver, a program provided by Geovariances. This program is installed with Isatis. If you have Isatis installed on the same machine as SKUA or GOCAD, there is no need to separately download and install them.

However, if Isatis is not installed, you can download GTXserver, free of charge, directly from the Geovariances Web site (www.geovariances.com). This program is available for several platforms.

To access the database, you need to first open a connection with the database and then use the GTXserver for loading or saving data. The connection closes once the load or save is done.

About the GTXserver

advanced parameters Typically, a new GTXserver runs from a location on your machine that is designated during the Isatis installation. Therefore, the default option in the Advanced parameters is Run GTXserver and the Force GTXserver check box is cleared.

Your particular situation may require you to set different parameters. For example:

•

If you do not have Isatis installed, but you have an Isatis database available, you can extract the GTXserver package from Geovariances Web site, select the Force GTXserver check box, and then type the path location of the executable file in the GTXserver box.

•

If you need to access a database stored on another machine, you may need to run GTXserver on that machine. You would click the Use already running GTX server and then type the entries for the Host Name and Port boxes.

•

If the Run GTXserver option is not working, the reason may be that it cannot be found due to a registry problem or an environment variable. To fix this, you can select the Force GTXserver check box and reset the location, or click the Use already running GTX server to run GTXserver manually.

The default values for the advanced parameters are set when you initially use the Export to Isatis dialog box. The parameters remain set, unless you change them. This prevents you from having to re-enter the same parameters multiple times.

Architecture of the

Isatis database In Isatis, the GTX_INIT directory contains all of the available studies (this directory is also known as $HOME/.isatis for Linux and %APP_DATA%\Geovariances\Isatisfor Windows). You can reference the location of this directory from the Isatis Help menu by clicking About.

The structure of each study is:

Isatis objects Isatis contains a set of files corresponding to SKUA and GOCAD object types. This table shows the relationship between SKUA and GOCAD objects and the corresponding Isatis file types.

SKUA and GOCAD object Isatis file type PointsSet or Well PointsSet

Curve Line or 2D fault

2D-Grid 2D regular grid

Surface 3D fault

Voxet 3D regular grid

Properties in the Isatis

database Properties can be attached to Grids, PointsSets, or Curves._{Isatis property types:}

•

Character variables (string)

•

1-bit variable, defines subsets of objects (equivalent to a region in SKUA and GOCAD)

•

Scalar variable

•

Macro variable for multi-realization property representation

This table shows the relationship between SKUA and GOCAD properties and the corresponding Isatis variables.

To export an object to

an Isatis file 1 Select File > Export >

Object Type (PointsSet, Curve, Surface, 2D-Grid, Voxet, SGrid, or Well) > Export Isatis to open the Export VSet to Isatis dialog box.

2 To set the advanced connect parameters, click Advanced to open the Advanced Connect Parameters dialog box.

Note step 2 and step 3 are necessary only if you need to edit these settings. Typically, you will not need to change the preselected settings.

2.2 Basic Procedures for Exporting Data 2-15 User Guide

3 Do the following:

a Click one of these options:

•

Run GTX server. Creates a new GTXserver instance (default).

•

Use already running GTX server box. Uses the GTXserver that is currently running.

b If you clicked the Run GTX server option, and you want to place the GTXserver in a location other than the default path, select the Force GTXserver check box. By default, this check box is cleared.

c If you clicked the Run GTX server option, and selected the Force GTXserver check box, enter the GTXServer path in the GTXServer path box.

Notes

• This path corresponds to the full GTXserver executable path. Normally, this path is in the bin directory of the Isatis installation path.

• You only have to force the GTXserver executable when you do not have Isatis installed. If Isatis is installed, GTXserver is automatically installed under Windows. • For Linux users, you may need to define the GTX_HOME environment variable and

then restart SKUA or GOCAD.

d If you clicked the Use already running GTX server option, and the GTXserver is running on another machine, type the name of the machine where the server in running in the Host Name box.

Note The default is localhost. If the GTXserver is running on your machine, skip this step. e If you clicked the Use already running GTX server option, and the GTXserver is

running on another machine, enter the port number in the Port box.

Note The port is the logical number on which a network program can choose to wait on.

The default port is 5500, Change this setting only if you use the "-port" option of GTXserver and you are running the server manually.

f In the DATA path box, enter the full data path. This path corresponds to the Isatis database directory.

4 Click Connect to connect to the GTXserver.

Note If the connection is successful, the dialog box is made available. If the connection is not

successful, the program displays a message indicating that the connection failed,

5 In the Study box, select the study where the object has to be saved. The list is activated if the selected database contains at least one study.

6 In the Directory box, select the directory of the selected study where you want to save the object.

7 In the Gocad Object box, enter the object name to be exported to Isatis. 8 To attach faults to the Isatis file, select the Store Faults check box. 9 In the Fault box, enter the faults to export.

Note You can export the fault curves or fault surfaces at the same time as the 2D-Grid. If you

are exporting a Voxet, this domain is not available.

10 In the Float variables box, enter the float variables to export. Variables are the equivalent of SKUA and GOCAD properties.

11 In the Regions box, enter the object regions to export to Isatis. 12 Click OK or Apply.
